FEEDING DEVICE FOR WIRE*COILING AND OTHER MACHINES.

SPECIFICATION forming part of Letters Patent No. 335,889, dated February 9, 1886.

Application filed July 28, 1882. Renewed July 12, 1884. Again renewed August 13, 1885. Serial No. 174,293. (No model.)

To all whom it may concern.-

Be it known that I, ORLANDO P. Bnrccs, of Chicago, in the county of Cool: and State of Illinois, have invented certain new and useful I Improvements in Feeding Devices for \Vire- Coiling and other Machines; and I do hereby declare that the following is a full, clear, and exact description thereof, reference bein had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

This invention relates to that class of wire feeding devices used to feed two wires forward simultaneously side by side in machines for coiling wire used in the manufacture of wovenwire mattresses or in other wire-working machinery.

In devices previously used for feeding wire in forced-feed coiling machines-that is to say, in machines in which the wire is pushed forward to a coiling-spindle--the wire passes from the reel to a pair of feed-rolls, between which it is grasped with considerable force, and by which it is forced forward upon the 2 coiling-spindle or within the coiling-cylinder,

as the case may be. To insure a proper pressure of the feed-rollers upon the wire, one of said rollers is usually made adjustable with reference to the other,a11d is borne against the wire by a spring or similar yielding device. In operating upon a single wire this feeding device works successfully; but when it is de sired to make a double coil by simultaneously feeding two wires side by side between the rollers of such device a serious obstacle to success has been found to result from the unevenness in the thickness of the two wires sought to be simultaneously coiled, or in the unevenness of the several wires, it being a 0 well-known fact that two wires of the same gage often vary slightly in diameter, and that the same wire will similarly vary at different points in its length. For the reasons above stated, one wire is liable at times to move 5 faster than the other, and to produce thereby unequal coils and a consequent waste of wire, or a defective fabric.

The unequal or very irregular feed produced by the use of ordinary feed-rollers has equally 5o objectionable effects in the operation of other machines as has been above described in connection with wirecoiling devices,and the present invention is intended to obviate the difficulties mentioned in all cases in which it is desired to feed forward two wires side by side 5 with regularity.

To this end theinvention consists, primarily, in a stationary feedroller and two yielding rollers opposed to the stationary roller, and arranged to adjust themselves independently to the several wires being fed forward thereby, as will be hereinafter more fully set forth.

In the accompanying drawings which illustrate one form of my invention, Figure 1 is a top or plan view of my improved machine. Fig. 2 is a vertical section through 00 ac ofFig.

1. Fig. 3 is a vertical section through y y of Figs. land 2.

A are the ends, and A the sides, of a rectangular open cast-iron frame, adapted to be secured to a suitable bench or other support, and having its sides A extended upward beyond the ends A, so as to afford relatively elevated bearings for the drive-shaft 1D and a transverse rollersh'aft,

B B are open rectangular cast-iron frames, two in number, fitted to set up into the re cesses a in the inner faces of the ends A of the main frame,and held in this position by means of removable lugs A placed one under each end of each frame B B.

C is a roller arranged on the shaft C and provided with hubs C, which fill the space between the opposite bearings C, and thereby retain the roller accurately in its central position, as shown. Said roller C is provided with two sets of gears, c,one on either margin of its periphery, in one of which meshes the pinion d on the driving-shaft D. Between the gears c c the roller 0 is faced to form a true 0 cylinder, and is provided with two circumferential grooves, c, proximate to each other and midway of the cylindrical face of the roller, as shown.

Beneath the roller C are arranged the two 5 equal rollers E E, mounted by the shafts E in bearings B in the upperhorizontal bars of the frames B B,about midway oftheir length, and axially opposite each other. Said rollers E E are provided with the cogs e, which mesh with too the corresponding cogs, c, of the roller 0, and have their inner faces in close proximity with each other, and in a plane which cuts the roller 0 between the grooves 0. Each of said rollers E is also provided with agroove, 6, near its inner margin and opposite the adjacent groove 0 of the roller 0. It is intended that the wires to be coiled shall be embraced in the opposite grooves c e, and compressed sufficiently to enable them to be carried forward by a rota tion of the rollers bymeans of the set-screws B, which pass through the lugs A and bear upward against the ends of the frames B B. Whatever yield may be requiredin the pressure of the rollers E is provided for in the sufficient elasticity of the bars of said frames B B, in which the shafts E of said rollers E are mounted.

S represents the coiling mechanism, of any suitable form, into the tube S of which the wires are forced by the feed-rollers, arranged and driven as described.

The rollers E E, being separate and separately yielding or self-adj usting, will manifestly adapt themselves to any variation in thickness of the wires being fed forward thereby, and, being driven at equal speed,will carry forward'said wires uniformly without reference to their relative diameters.

The device embodying my invention, as

herein illustrated and described in connection with a wire-coiling machine, may obviously be used with the same advantageous results in connection with other kinds of machinesas, for instance, with machines for making barbed fence-wire.

I claim as my invention-- 1. A device for simultaneously feeding two wires side by side to a wire-coiling or other machine, comprising a stationary roller, 0, and two separately and self adjusting rollers, E E, substantially as and for the purpose set forth.

2. In a device for simultaneously feeding two wires side by side to a wire-coiling or other machine, the combination, with the frame A A, which supports the stationary roller, of the open removable frame composed of the bars B Band connecting parts B, and having the adjustable roller E, mounted on the bar B between its ends, whereby the elasticity of said bar affords the required adjustment of the roller E when the machine is in operation, substantially as described.

In testimony that I claim the foregoing as my invention I affix my signature in presence 5 5 of two witnesses.
